(54) Method of converting two-dimensional images into three-dimensional images


(57) In a first method of converting two-dimensional images into three-dimensional images according to the present invention, when the movement of a main image is fast, a main image signal is written into field memories for each field. When the movement of the main image is slow, the main image signal is written into the field memories at intervals of a predetermined number of fields. An image to be read out as a sub-image from the field memories is determined on the basis of the speed of the movement of the main image.
